When searching for "Virginia", the first result is the Dutch Wikipedia page on the US state, which is expected.
However, the summary reads (translated from Dutch):
"Virginia is the oldest and most populous state of the United States, named after Queen Elisabeth I. Read about the colonial period, the American Independence War, the Civil War, slavery and the geography of Virginia."

This is clearly wrong, because Virginia is not the most populous state of the United States, California is. The underlying article does not contain the cited description, nor does it make any mention of Virginia being the most populous state. Therefore I can only assume that this description was AI-generated and contains hallucinations.
I'm not always going to click through and read the entire article. This time, the error was obvious to me, but for all I know it may happen for anything. And with Wikipedia's name next to the description, my mind automatically lends credibility to the statement, even though it was made up and did not come from Wikipedia. If I cannot rely on search result descriptions being representative of the page behind them, that reduces Kagi's reliability as a search engine for me. My suggestion would be to use the page's <meta name="description"> value instead, or at least provide us an option to prefer that over the AI-generated descriptions.
